SPY Historian Vince Houghton sat down with Paddy Hayes to discuss his book Queen of Spies: Daphne Park, Britain's Cold War Spy Master. Hayes recounts the fascinating story of the evolution of the British Secret Intelligence Service (SIS) from World War II to the Cold War through the eyes of Daphne Park, one of its outstanding and most unusual operatives. He gives one of the most intimate narratives yet of how the modern SIS actually went about its business whether in Moscow, Hanoi, or the Congo, and shows how Park was able to rise through the ranks of a field that had been comprised almost entirely of men. Queen of Spies captures all the paranoia, isolation, deception of Cold War intelligence work, and combines it with the personal story of one extraordinary woman trying to navigate this secretive world.
